WebDescription. Use the Hardware Interrupt block to create an interrupt service routine (ISR) automatically in the generated code of your model. The ISR executes the downstream function-call subsystem associated with event ports of the block. The function call subsystem associated with the event output port run at same priority as that of ISR priority. WebC interrupt handlers cannot be produced in this way using tcc. The __irq keyword is faulted by tcc because tcc can only produce Thumb code, and the processor is always switched …
